To all whom it may concern.'

Be it known that I, VAN EMERY EASTER- DAY, a citizen of the United States, and a' resident of Urbana, inv the county of Champaign and State of Illinois, have invented certain ynew and useful Improvements in Building-Blocks, of which the following isv a specification.

My present invention relates generally to building blocks, and more particularly wall blocks, my object being the provision of a simple inexpensive block which can be manufactured of light weight, will be strong and durable, and by means of which blocks in a wall may be securely locked, in addition to the mortar bond.

With this general statement in mind my invention resides in a building block of the structure to be now described with respect to the accompanying drawing, which forms a art of this specification, and in which,

4igure 1 is a rear elevation of my improved bloclr,

Fig. 2 is a longitudinal line 2--2 of Fig. 1,

Fig. 3 is a transverse section taken on line 3-3 of Fig. 1, and

Fig. 4 is an elevation of a section of wall formed by my improved blocks.

Referring now to these figures and particularly to Figs. l to 3 inclusive my invention proposes a hollow block generally indicated at 10, and hollow by virtue of cells or cavities' 11 extending therein from its rear face and partiallyV therethrough, leaving its front face 12 solid and unbroken, like its sides and ends. As particularly shown, the cells or cavities 11 are preferably tapered so that the block when molded may be readily withdrawn from mold cores and the like without danger of cracking or breaking.

In the front face 12 of the block reinforcements 13 and 14 are embedded, the reinforcements 13 being in the nature of U-shaped rods, whose extensions project parallel with one another and with the end surfaces of the block, parallel to the latter, and having projecting ends 15 which extend beyond the lower face of the block adjacent to its ends.

Theother reinforcement 14 is in lthe nature of an elongated rod extending lengthwise of the block adjacent` to its lower surface and provided with an extension 16 at one end projecting beyond the adjacent end of the block, its opposite end terminating section taken on short of the opposite end of the block so as to leave space for a recess 17 the depth of wh1ch at least equals the length of the extension 16.

In lts upper side face the block 10 has an elongated recess 18 in the same plane with the U-shaped reinforcement 13, so that when blocks 10 are laid in break-joint relation in a wall as seen particularly 1n F ig. 4, the recesses 18 of one block will receive therein the extensions 15 of the adjacent ends of end wlse abuttin blocks thereabove, the recess 17 o f each b ock receivin the laterally projecting extension 16 of t e reinforcing rod 14 of the next adjacent block at oneside thereof.

In this manner it is obvious the blocks will be more or less automatically leveled in the wall courses and locked against relative displacement without depending upon the mortar bond between the blocks to the extent this mortar bond is depended upon at the y present time.

It will be noted that the recess 18 of each block is of suilicient length to admit of a certain amount of endwise relative movement of adjacent blocks, and it should be understood that while I have shown a preferred arrangement of blocks in a wall, and a particular manner of extending the reinforcing members to adapt them to such a Wall construction, my invention contemplates that the block may be utilized in various different arrangements and that the reinforcing members may be extended through its various sides to adapt the same to different arrangements.

I claim: l

1. A building block having a rectangular body provided with cavities'extending therein from one side and terminating short of its opposite side whereby to lea-ve a'solid slab closing the last mentioned side of the body, a U-shaped reinforcing member embedded in the said solid slab parallel to the last mentioned side of the body, with its angular portions disposed around and beyond the limits of the said cavities and terminating in parallel extremities projectin beyond one face of the block parallel wit and adjacent to opposite ends of the block, the opposite face of the body of the block having a lengthwise recess located at an a proximately central point between its en s, in the plane of the said reinforcing member, for the purpose described.

in from one side and terminating short of its opposite side whereby to leave a solid slab closing the last mentioned side of the` body, a U-shaped reinforcing member embedded in the said solid slab parallel to the last mentioned side of the body, with its angular portions disposed around and beyond the limits of the said cavities and terminating in parallel extremities projecting beyond one face of the block parallel With and adjacent to opposite ends of the block,

the opposite face of the body of the block having a lengthwise recess located at an a proximately central point between its en s, 1n the plane of the said reinforcin member, and a reinforcing rod extending ongitudinally through the block body and crossing the extensions of the U-shaped member adjacent to the said extremities of the latter, said rod projecting at one end beyond one end of the block and having its opposite end .terminating in a recess in the opposite end of the block as described.
